Benefits of technology
[0028]In some embodiments, the first and second sheets are deployed substantially simultaneously so that the first sheet is deployed in a first direction from the housing and the second sheet is deployed in an opposite direction from the housing. By using such an arrangement, which is described in greater detail below, the angular momentum imparted by deploying the first sheet can be canceled by the angu
Problems solved by technology
The common approach has limitations in how compactly the arrays can be packaged, because of the inherent volume and inflexibility of the rigid panels that are used as mounting substrates for the photovoltaic assemblies.
Such flexible membrane solar arrays with discrete and separate super-structures are limited in the shielding provided to the backside of the solar array after deployment, and by the complexity of deploying such an array with tensioning interfaces between the deployable boom and the nonstructural solar array blanket.
Although there is a desire to provide power for CubeSa

Embodiment Construction
[0049]Details of the present invention will now be described including exemplary aspects and embodiments thereof. Referring to the drawings and the following description, like reference numbers are used to identify like or functionally similar elements, and are intended to illustrate major features of exemplary embodiments in a highly simplified diagrammatic manner. Moreover, the drawings are not intended to depict every feature of the actual embodiment nor the relative dimensions of the depicted elements, and are not drawn to scale.
[0050]In the most general terms, the present disclosure relates to deployable booms associated with vehicles or permanent structures, the booms being structured components, or assemblies including, in some embodiments, transducers for collecting or emitting electromagnetic energy. One embodiment of the present disclosure depicts a space vehicle such as a satellite, in which the boom enables a compact stowed configuration of the deployable assembly during...

Abstract
The present disclosure describes a method of deploying an extensible boom from a housing. Sheets supporting respective arrays of photovoltaic devices are deployed substantially simultaneously so that a first sheet is deployed in a first direction from the housing and a second sheet is deployed in an opposite direction from the housing. Angular momentum imparted by deploying the first sheet is canceled by angular momentum imparted by deploying the second sheet. The housing can be part of a space satellite, such that the first and second sheets are deployed without causing the satellite to move out of its orbit.
